Comparing and ScalingBig IdeaMany important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should
use them.
Investigation 4: Comparing by Finding Rates Essential Question: What methods are there for comparing things?
4.3 solving problems with rates
A. make a graph showing Sascha's total distance traveled over time. Use 5-minute time intervalson the x-axis. B. How far did Sascha travel in his 1-hour ride? Explain.
He traveled 27.48 miles per hour. I got the answer by taking the amount of miles and dividing them by 60. Then I multiplied that answer by the amount of minutes that Sascha went during that interval.
C. If you could maintain a steady speed of 13miles per hour on a bike, how long would it take you to travel the same distance Sascha traveled in 1 hour ride?
It would take me about 2 hours, becuase 13 divided by 60 = 0.216 x 120 = 26 miles, so it would take you about 2 hours.
D. If you were racing Sascha, what constant (steady) speed would you have to maintain to tie him?
You would have to go about 27 miles per hour the whole time.
